METHOD OF PRINTING WAR?.

Application filed January 2, 1914.

To all whom it may concern.'

Be it known that I, GEORGE H. "WIN snow, a citizen of the United Statesof America, residing at South Hadley Falls, in the county of Hampshireand State of Massachusetts, have invented a new and useful Method ofPrinting Varp, of which the following is a specification.

My invention relates to improvements in methods of printing warp for usein the manufacture of cloth or fabric of different kinds and grades, andconsists in general and essentially in treating the warp-units to causethem to adhere to each other laterally so as to form a flat sheet, stripor web, in completely drying such web on one side while leaving theother side moist, in print ing, on or, applying the color to the dryside of such web, and in setting the color, all as hereinafter set'forth. Since one side of the warp is moist at the time the color isapplied to the dry side, said color strikes into said warp and comesthrough on the other or moist side.

In the past many unsuccessful attempts have been made to produce aprinted warp which, when Woven into cloth, discloses or presents theidentical pattern on both sides of the fabric, it having been necessarynot only to have recourse to a number of disconnected, and it mightalmost be said unrelated. operations, separated by considerableintervals of time, but to employ a variety of different and independentmachines, for producing even the imperfect product heretofore broughtforth. The several operations involved in previous methods includedsizing the warp, drawingin, placing the warp in a loom to weave threadsacross it at certain intervals for the purpose of retaining thewarp-units in place for printing, removing the warp from such loom andprinting, again drawing-in. and placing said warp in said loom thesecond time for weaving1 at which time or during the weaving operationthe threads that were first Woven in having to be taken out as they arereached, which caused imperfect or defective places to appear in thecloth, and a loss of production by the stopping of the loom for thispurpose.

With my method. whereby or wherein the warp is completely dried on theside to be printed. between the sizing and printing Steps, next dried,.then alternately steamed Specification of Letters Patent.

and dried, and finally thoroughly dried and made ready to wind on theloom-beam, all in one run or by a series of correlated, naturallysequential, and continuous steps, I overcome the serious objectionspointed out above and consequently very materially decrease the cost ofproduction, increase the product, and produce a warp with which aperfect fabric can be manufactured, and this is the primary object of myinvention.

By partially drying the warp so that one side is completely dry, aftersaid warp has been treated with size or gum to cause the warp-units toadhere to each other and before said warp has the pattern printedthereon, a suitable printing surface is obtained and said warp isprepared to take the color in such a manner as to produce said patternon both sides alike, and if a Warpunit rolls during the subsequentweaving process no break is produced in the pattern. This is a mostimportant and valuable feature of my invention, and in connectiontherewith it should be observed that, inasmuch as the warp receives thecolor on the dry side, such side comes next to the color applying memberand does not have a tendency to adhere to the same, by reason of theadhesive material in said warp, or to deposit such material on suchmember. It is practically impossible to apply color evenly, sharply, andsuccessfully directly to a moist surface, because in such case the colorwill run and spread laterally, instead of producing a clear-cut surfacepattern and striking through to produce such pattern throughout the Warpand on the other side, as is done when the side to which the color isdirectly applied is dry and the other side moist at the time ofprinting. Thus it is seen that, by completely drying the side of thewarp to be printed, T remove all danger of spoiling the pattern on theprinted side and therefore on both sides and throughout the warp. Bythis method the color in the warp is set therein so that it will not runor bleed in finishing the Woven fabric. This obviates the necessity ofsteaming the cloth after it is woven.

It is to be understood that the term color is herein used in its broadsense, and signifies any single color or shade or any combination ofcolors or shades or both.

Other objects and advantages will appear in the course of the followingdescription.

I attain the objects and secure the advantages of my invention in themanner herein set forth, and by means such as those illustrated in theaccompanying drawings, in which- Figures l, lr1 and lb togetherconstitute a side elevation of a machine which may be practically andprotably employed in carrying out my method.

Similar figures refer to similar parts throughout the several views. A

In Fig. l, the side of the steam-box, which is next to the beholder, isomitted to disclose the interior of suoli boX and its contents, and oneof the cylinder connections is shown in section, thus bringing clearlyinto view the steam passage in and through such connection. In Fig. la,a part of the size-box is broken out to show the guide-roll which takesthe warp down into the size.

The directions of moving parts and members are indicated on the drawingsby arrows.

Although I have shown and will describe a practicable and eflicientmachine to aid in giving effect to my method, I do not thereby restrictthe method or its application and use in any way.

I will first describe the method in detail and will then explain themachine, illustrated in the accompanying drawings, and the manner inwhich the method is carried out withthe aid of such machine.

rPhe first step in the method consists in applying adhesive material toa series of warp-units, which units have been properly arranged side byside in readiness for printing. The warp-units are usually conductedfrom a series of section-beams, through one or more reeds, to andthrough a size-box and its rolls, for the purpose of arranging suchunits in proper formation and applying the adhesive material thereto.The warp-units are now saturated with the adhesive material, such as asize or gum which is prepared for this particular purpose, and saidunits adhere to each other laterally so that they form a practicallyunbroken strip or web, and this web is next completely dried on oneside, preferably b v being carried over or brought into contact with acylinder which is heated to the proper temperature to produce thepartial drying effect desired, that is, partially with reference to theweb as a whole. This is the second step in the method. As the third stepin the method, the warp, which is now dry on one side and moist on theother, has applied to the dry side color wherewith the printing orpattern is produced, such pattern being even, sharp, and uniform byreason of the fact that the side to which it is applied is dry, aspreviously observed. Owing to the fact that the warp is dry on the sideonly which receives the color, said color strikes through or penetratesthe moist portions of said warp and appears on the side opposite to thatwhere it is applied. Thus the warp is colored or printed alikethroughout. The printed warp is now dried as another' step in theprocess, such drying usually being effected through the medium of one ormore drying cylinders. After being thus dried the warp is alternatelysteamed and dried or partially dried to fix or set the color, the dryingand steaming alternating on the opposite sides of Said warp, aft-er aninitial steaming and followed at the end by a final steaming. This is animportant step and may be carried out with the aid of a steam-box and aseries of steam -heated cylinders in said box. Following andsupplementing the last-mentioned step is a final drying of the warp,which may be brought about by means of a heated cylinder. Although thefinal drying might be considered as the last step in the method, themethod may be extended to include measuring the number of yards and thelength of the cuts or pieces therein, separating the warp-units so thatthey can be used for weaving, and winding such units on a loom-beam.While this constitutes the method in detail, it isapparent that somedeparture therefrom may be made without violating the spirit of myinvention.

Passing now toA the machine, it may be somewhat brieflv described asfollows1- Situated approximately in the center of the machine lengthwiseis a printing-mechanism frame l. Supported by one side of the frame l isone end of a shaft 2, the bearing for the other end of said shaft notbeing shown. Mounted. on the shaft 2 are a pulley 3, a sprocket-wheel4l, and a pinion 5. Power from any suitable source is applied to thepulley 3, and it is from this point that the entire machine is driven.Power is transmitted to all parts of the machine, except to the printingmechanism which is driven by the pinion 5, through the medium of thesprocket-wheel 4, a sprocket-chain 6, a series of sprocketwheels 7,countershafts 8, sprocket-chains 9, and other driving membershereinafter more particularly pointed out. vThere are five countershafts8, and the middle one is that driven by t-he sprocket-chain 6 and whichin turn drives the other four. All driving and driven parts are so timedthat at no place does any undue strain come upon the warp.

The numeral 1() designates the Warp.

A hanging bearing l1 is provided for each end of each countershaft 8,such bearing being secured to the upper framework of the machine, whichis represented at 12.

Depending from the frame-work 12, near the front end thereof and on eachside, is a llt bracket 13, the rear end of the horizontal arm of suchbracket being attached to a steam-box 14. Back of each bracket 13 and inthe rear of the transverse center of the machine is a U-shaped bracket15, that depends from the franiework 12 and has a horizontal cross-piece16 near the top. At the rear of the machine on each side are twouprights 17 and 18.

Journaled in a bearing 19, on the front of each bracket 13, is a hollowtrunnion 20 of a steam-heated cylinder 21. This cylinder is associatedwith the steam-box 14 and a Series of cylinders 22 therein. Having itsshaft 23 journaled at each end in a bearing on the bottom member of eachbracket 13 is a guide roll 24. Journaled in a bearing 25, on the front0f each bracket 15, is a hollow trunnion 26 of a steam-heated cylinder27, and in a similar bearing, on the rear of said bracket, -is a hollowtrunnion 28 of a steam-heated cylinder 29. The cylinders 21, 22, 27 and29 are for drying purposes, and the last-mentioned cylinder is thatwhich partially dries the warp as the latter passes over it. instead ofeffecting the complete drying of a moving element as do the cylinders 21and 27, for which reason said cylinder 29 is termed the half-dryingcylinder. A guide roll 30 has its shaft 31 journaled at each end in abearing on the bottom member of each bracket 15. and a guide roll 32 hasits shaft 33 journaled at each end in a bearing on each member 16. Onthe back of each bracket 15 are bearings for the shafts 34 and 35, ateach end. of a guide roll 3G and a guide roll 37, respectively. Abearing on the back of each upright 17 supports one end of the shaft 38of a guide roll 39, and a similar bearing on the back of each upright 18supports one end of the shaft 40 of a guide roll 41.

A system of steam pipes is provided to heat the several drying cylindersand other parts of the machine where heat is required and for supplyingfree steam where it is needed, and the live-steam pipes of such systemare designated by the numeral 42, and the exhaust-steam pipes by thenumeral 43. Steam from any suitable source of supply is introduced at44, Fig. 2, into the live-steam pipes and the exhaust steam escapes fromthe pipes 43 at the point 45, in said view. or is led away through pipes(not shown) from such point. The pipes 42 are supplied wherevernecessary with valves 46, and safety-valves 47 are provided at suchpoints as may be necessary or desirable. Live steam enters thehalf-drying cylinder 29 at 48, it enters the cylinder 27 at 49. and thecylinder 21 at 50. The exhaust steam escapes from the aforesaidcylinders at the end 0f each which is opposite to that where the livesteam enters.

lVithin the steam-box 14 is a pair of stand-pipes, one of which appearsat 51 in Fig. 1. Live steam enters the standpipe 51, which is shown, at52, and exhausts through the stand-pipe on the other side at the pointindicated at 53. Live steam enters the steam-box 14 at 54, and exhauststhrough a pipe 55 at the top of said box. On the front and back of eachstand-pipe 51 is a series of brackets 56 for the support of the hollowtrunnions 57 at the corresponding ends of the cylinders 22. Each bracket56 has a passage 58 therein which opens at one end into the stand-pipe51, to which said bracket is attached. and at the other end into theopen terminal of the trunnion 57 journaled in such bracket.

Live steam entering the right-hand standpipe 51 at 52, rises in saidpipe, passes through the passages 58 in the several brackets 56 attachedto said pipe and enters the cylinders through their trunnions 57 intowhich said passages open. From the cylinders 22 the steam escapesthrough the trunnions and the passages in the brackets at the oppositeends of said cylinders into the stand-pipe on the opposite or left-handside, and escapes from said last-mentioned stand-pipe at 53. In thismanner and by this means the cylinders 22 are heated to the necessarydegree of temperature.

Each of the cylinders is provided at one end with a gear Two of thegears 59 on the front are driven in oppesite directions by a pinion 60which is secured to a shaft 61 that is journaled in the steambox 14.Secured also to the shaft 61 is a sprocket-wheel 62, and asprocket-chain 63 drives said sprocket-wheel from one of thesprocket-wheels 7 on the second countershaft 8, the counter-shaft 8 atthe front end of the machine being considered as the first. The uppergear 59 which is iny mesh with the pinion 60. is also in mesh with thetwo upper gears 59 and so drives them both in the direction opposite tothat in which said :i

first-mentioned gear is driven by said pinion. The remaining gears 59 inthe train are in mesh one with another on opposite sides of the verticalplane between the axes of the stand-pipes 51, so that each gear belowand on the opposite side relative to the next adjacent gear above isdriven by the latter in the opposite direction thereto. commencingwiththe second front gear from the top` which is driven by the second reargear from the top. By this arrangement is maintained or secured the feedfor the warp 1() in the steam-box 14. which said warp enters at 64 andpasses directly to thc lowermost cylinder 22. then takes a serpentinecourse over and under or partially around the cylinders 22, and finallyafter passing over the uppermost cylinder leaves said box at Theprinting mechanism consists in part of a felt-covered cylinder 0G whichis mounted on a shaft 67 that is journaled at each end in abearing-block 08 arranged to slide vertically in a slot 69 in each sideof the frame 1. A backing-cloth. or the gray as it is called. 70. isrequired to prevent theI wai'p 10 from coming into direct contact withthe felt surface of the cylinder 66. The gray T0` starting from a roller7l at the back end of the machine. upon which said gray is wound. passesupwardly. through a series of tension barsl 72 fastened to the i'earsides of the uprights 1T. to and over the guide roll 39, then forwardlyto and ovei' the guide roll 37 and downwardly under and over twospreading bars 73 fastened beneath the brackets 15. thence under thecylindei' (36 and up and over the drying cylindei' 27 to a guide roll74. next upwai'dly and rearwardly past the guide roll 30 and in contacttherewith and ovei' the guide roll 30 to the guide roll 41. and finallydownward through a series of tension bars 75 to be wound on a roller T6.The roller T1 has a shaft which is journaled at each end in a bearing TTon the back side of the corresponding upi'ight 1i'. The tension bars 75are fastened to the uprights 18. The guide roll 74 has a shaft 78journaled at each end in a bearing 79 located at the lower front cornerof each bracket 15. bar S0. having each end attached to one of theuprights 1T. assists in supporting the gray on its return.

rewinding apparatus or mechanisln is provided for the gray T0. and suchmechanism comprises a fi'ame 81 having mounted therein a friction rollera holding bar 83 at each end. and a latch S1- also at each end. togetherwith means Yfor di'iving said roller. The roller 82 is mounted on ashaft S5 which is liournaled in the frame Sl. Each bar 83 is pivoted at86 to the contiguous end of the frame Sl. and each latch Sl is pivotedat Si' to such end of said frame. The parts form a vertical slot SS ineach end of the frame Sl in which is received the protruding terminal ofa shaft S9 en which the roller 'T6 is mounted. The roller 70 and theconvolutions of the gray 70 thereon rest on the roller 82. and as saidi'ollei' S2 is rotated the members above are also rotated to wind upsaid gray after it has passed through the printing mechanism and soserved its pui'- pose. The i'oller is driven in the proper direction torewind the gray by means of a pulley 90 secured to the shaft 85, apulley 91 secured to the rearnmst countershaft and a crossed belt 92which connects said pulleys. As the size of the roll above the roller 82increases the shaft 89 moves upwardly in the slots prepared for it.rl`he aforesaid roll can be removed by releasing the holding bars S?)from the latches 84.

ln passing around the drying cylinder 2T the gray 70 is dried so that itwill not mildew after being wound on the roller 76. The dainpness whichthe gray receives and which is removed by the cylinder 27 comes fi'omthe color applied to the warp during the act of printing. Next in orderforward of the gray-handling apparatus is a rack 93 for a series ofsection-beams 94 from which the warp l0 starts. The sectionbeams 94 haveshafts or trunnions 95 which are journaled in suitable bearings on theiframe 93. and each of such beams is provided with a weight 96 and ai'ope 9T to form what is commonly known as a dragrope tension.

At 98 ai'e shown a plurality of guide rods for the warp-units fromcertain of the section-beams.

In front of the section-beams 94 is a leasing-reed 99. and next inorder, when the same is required, is an adjusting reed 100. The reeds 99and 100 are supported on a pair of rods 101 that extend rearwardly froma size-box 102. Each rod 101 is supported at the rear end by an upright103. The leasing reed 99 is of ordinary construction. and the objects ofthe same are to retain the warp-units in position for printing. and formaking the weavers lease on the loom-beam. The adjusting reed 100 is forthe purpose of accurately guiding the warp-units when stripes are to beprinted thereon. This i'eed is necessarily adjustable. as will bereadily understood,

The size-box 102 is provided at the i'eai' with a guide roll 10J( and infront of this with a guide roll 105. also with a guide i'oll 100 insideand below the surface of the size or gum which said box contains, andwith a pair of under squeeze-rolls 10T and a pair of upper squeeze-rolls101%. The squeezerolls 10T are mounted on shafts 109 which are journaledin the sides of the size-box 102. and the squeeze-rolls 108 are mountedon shafts 110 which are i'e;:eived in slots in the upper edges of saidsides. Steam enters the size-box at 180.

The warp l0 passes forward from the section-beams 91 to and through theleasingreed 99. and to and through the adjusting reed 100 if present.over the guide rolls 104 and 10T. down under the guide-roll 10G, andupwardly and forwardly between the rear squeeze-rolls 10T and 10S andthe front squeeze-rolls 10T and 109. The warp is saturated with the sizewhen it passes under the roll 100. and the surplus size is squeezed outof said wai'p by the rolls 10T and 10S. lit is here that the first stepin the method occurs. The squeeze-rolls 10T are driven by means of gears111 on the shaft 109. an intermediate gear 112 mounted on a stud 11?projecting from the size-box 102. said intermediate gear being in meshwith said firstn'ientioned gears. a gear 114 ou a shaft 115 which isjournaled beneath said boX, said gear 114 being in mesh with said gear112, a sprocket-wheel 116 on said shaft 115, a sprocket-chain 117, and asprocket-wheel 118 on the fourth countershaft 8. As the squeeze-rolls107 are driven, by means of the mechanism provided for that purpose, thesqueeze-rolls 108 are actuated and the warp 10 is drawn through thesize-box and the adhesive material therein. The warp passes out of thesize-box over the front of the forward squeeze-roll 10S, and is then ina thoroughly sized condition, with the warpunits adhering to each other.

It may be remarked in passing that, in order to prepare the warp forprinting and for weaving after it is printed, it is necessary to applythereto adhesive material of a suitable character. lVithout properlysizing the warp it would be quite impracticable if not impossiblesuccessfullyY to apply color thereto.

From the size-box 102 the warp 10 passes upwardly and rearwardly to thehalf-drying cylinder 29, over the same and downwardly and forwardly tothe cylinder 6G. The heat of the cylinder 29 is so regulated that inpassing over said cylinder the warp is dried only on the side whichcomes in Contact with said cylinder, while the other side of said warpis left in a damp condition. Here occurs the second step in the method,and it is by reason of this step or as a result of the same that thewarp is so prepared as to make it possible for the color, which issubsequently applied to the dry side of said warp, to produce thedesired effect on said side and strike through and thoroughly penetrateand permeate the warp-units, with the result that the pattern printedthereon shows alike on both sides of the cloth woven with said units asthe warp thereof. Besides this very important feature or result, whichemanates from the presence of the half-drying cylinder and the step inthe method which said cylinder is instrumental in inducing, there is theother advantage hereinbefore noted, which is that the size on the sideof the warp that comes next to the printing-roll or -rolls is dry, hencedoes not stick to such roll or rolls.

There is involved in the third step in the method the printing mechanismof the machine, and this mechanism comprises, with the frame 1 and thecylinder 66, a printingroll 119, a doctor 120 for such roll, a colorbox121 having a furnisher-roll 122 therein, and driving mechanism. Thecolor-box 121 is supported within the frame 1, and the furnsher-roll 122is in Contact with the engraved roll 119 above. The furnisher-roll 1.22is mounted on a shaft 200 journaled in the box 121, and said shaft isdriven by a gear 201 thereon and a gear 202 on the engraved-roll shaft131. The furnisher-roll transfers the color in the box 121 from such boxto the engraved roll 119 and keeps the latter filled or supplied. Theremay be more than one printing or engraved roll. 'lhe doctor 120 ismounted on a rod 125 which is journaled in the frame 1 behind theprinting-roll 119, said doctor serving the usual purpose of such adevice. A Vertical screw 126 is tapped into and through a cap 127, oneach side of the frame 1, to bear on the block G8 in the slot 69 undersaid cap. Means is provided for elevationg the shaft 67 and the cylinder60, when it is necessary to do so and the screws 126 are turned up. Saidmeans comprises a lever 128 mounted at 129 on the frame 1, and otherparts which need not be described here.

The printing-roll 119 is driven by means of a gear 130, on the shaft 131upon which said roll is mounted and which shaft is sup .f

ported as is customary upon weighted levers, one of which is representedat 121Y mounted on a rod 123, in Fig. 1, an intermediate gear 132carried on a stud 133 which projects from said frame, and the gear 5.The gears 130 and 202 are on opposite ten minals of the shaft 131. Thecylinder 6G is actuated by the gray and the warp 10 and the frictionalcontact of the parts with the printing-roll. The cylinder 27 is ac- Ituated by the gray and warp, and the latter alone rotates the cylinder29. '1 he printingroll 119 and the cylinder 66 revolve, of course, inopposite directions. The gray 70 passes under the cylinder 66 in contactwith the surface thereof, and the warp 10, after leaving the half-dryingcylinder 29, passes under said cylinder in contact with said gray, andtravels with the latter up, over and partly around the drying cylinder27 to the guide roll 7-1, thence rearwardly to the guide roll 30. At theguide roll 30 the gray 70 and the warp 10 separate, the formercontinuing rearwardly over the guide roll 37. and the latter passingupwardly over the guide roll 32 and then forwardly to a drying cylinder131. 1n passing over the cylinder 27 on the gray 70 the warp is driedsufficiently to prevent it from marking off or smearing the rolls 74, 30and 32 which it contacts with on the way to the cylinder 134. The warpis between the rolls 71 and 30 and the gray, as it will be seen mustnecessarily be the case when it is remembered that the warp and grayturn rearwardly after passing the cylinder 27 with the gray between saidcylinder and said warp or on the inside.

The next step, that of completely drying the warp after it is printed,is taken or effected, so far as this machine is concerned, with the aidof the drying cylinder 131 and another drying cylinder 135 behind saidcylinder 134. A frame 136 is provided forward of the frame 1 for thecylinders just mentioned. The frame 136 has a bearing 187 for a hollowtrunnion 138 at each end of the cylinder 131, and a bearing 139 for ahollow trunnion 11() at each end of the cylinder 135. Live steam entersthe cylinder 135 at 111 and exhausts at the opposite end of saidcylinder, and live steam enters the cylinder 131 at 112 and exhauststhrough the opposite end thereof. guide roll 113 is mounted on a shaft111 which is journaled in the frame 136 at the back end. Asteamregulator 115 is provided for the live-steam pipes 13, which supplysteam to the cylinders 131 and 135, to control the pressure in saidcylinders.

The cylinder 131 is driven by means of a sprocket-wheel 117 secured onone of the cylinder trunnions 138, a sprocket-chain 118. and asprocket-wheel 11S.) secured to the ccuntershaft 8 above said cylinder.The cylinder 135 is rotated by the warp in passing over the same. Thevarp 10 passes down over the front of the cylinder 131 and under thesame in a rearwardly direction, then up over the cylinder 135 and downbelhind and under the guide roll 113, thence forwardly beneath saidcylinders to the steam-box 11 which it enters at 61. Being thoroughly,dried by the cylinders 181 and 135, the warp is ready for the next stepor for the treatment in the st am-box 11, whiclr follows.

1n taking its tortuous course through the steam-box 11 in contact withthe cylinders 22, the warp 10 is subjected both to the heat of saidcylinders and the steam in said box, with the result that the color insaid warp is set in a most perfect and lasting manner. The steam in thebox 11 is at low pressure, while that in the cylinders 22 is at highpressure, and the warp in its course at this time is first dampened orsteamed on both sides, and then, upon arriving` at the lowermostcylinder is subjected to the heat thereof applied directly to one sideof said warp. Next this side of said warp is exposed to the steam in thebox and the other side is brought into contact with the second cylinder22 in the direction taken by the warp, and these alternate doubleexposures occur until the warp leaves the uppermost cylinder 22 andpasses out of the boX through the opening 65, the last exposure in saidbox being to the steam therein on both sides of the warp. Upon emergingfrom the front of the steam-box 11` the warp passes forward to thedrying cylinder 21. lhile in contact with the cylinder 21 the warp 10 isthoroughly, completely and finally dried, the steam which was taken upthereby in said box being entirely driven off. It is by this means andin this manner that not only is the required setting of the colorproduced, but also the final drying which obviates any liability tomildew on the part of the warp after being wound on the loombeam.

The act of passing over the cylinder 21 to be dried constitutes a stepthat is supplementary to the act of passing through the steam-box 11,and might be considered as a part of the color-setting or -iixing step.The warp 10 travels rearwardly and forwardly under and with the cylinder21, after passing over the upper and front portions thereof, and uponleaving said cylinder passes to the guide roll 21 and over the same.From the roll 25 the warp 10 in this case drops to a measuring-roll 150at the rear end of a section of the machine which comprises a number ofother elements besides said measuring-roll, a loom-beam. 151 at thefront of the machine and of said section being included aniong suchelements. The elements at the front end of the machine are supported bya frame 152. and may be said to include. besides the measuring-roll 150and the loom-beam 151, a second measuring-loll 15?), two splitting-rmls151, an expansioncomb 155, and draft rolls 156. 157 and 158. Each of themeasuring-rolls 156 and 1521 has a shaft 15S) which is journaled inbearings 16() on the frame 152. The splitting-rods 151 are supported inholders 161 mounted on brackets attached to the sides of the frame 152.one of such brackets appearing at 162. The second-measuring-roll is infront of the first, the splitting-rods are ahead of said second roll andarranged one forward of the other. Next is the expansion-comb 155 whichis mounted at each end in a support 163 on the frame 152. In front ofeach support 163 is a bearing 161 for one end of a shaft 165 upon whichthe roll 156 is mounted. The roll 157 is mounted below the roll 156 on ashaft 166 which is journaled in the frame 152. and the roll 158 ismounted on a shaft 167 which also has its bearings in said frame. Theroll 158 is at the front end of the frame 152, and is in contact withthe roll 157, as also is the roll 156, in the absence of the warp 10.The warp-beam 151 is in front of the roll 137 and below the roll 158.The warp-beam has suitable axial supports, one of which appears at 168and is journaled in a forwardly-extending bearing bracket 1.69 at thefront end of the frame 152 011 one side. The axial support 168 is afriction member which is capable of revolving the warp-beam 151, andsuch support has a gear 170 secured thereon. A shaft 171 is ournaled inthe frame 152 below the shaft 166, and carries at one terminal asprocketwheel 172 and at the other terminal a pinion 173. Asprocket-chain 171 drives the sprocket-wheel 172, the shaft 170 and thepinion 173 from a sprocket-wheel, on the foremost counter-shaft 8.similar to the sprocket-wheel that is shown thereon at 7. There is agear 175 which is secured on the shaft 166 and is in mesh with thepinion 173 and with the gear 170. Thus the roll 157 and the frictionmember 16S for the warp-beam 151 are dri\en positirely, while the rolls156 and 158 are actuated by reason of their contact with said roll 157,or by the warp 1() in traveling over said rolls 156 and 158, aided bysaid roll 157. The measuringrolls are actuated by the moving warp. Thewarp-beam is not driven positively by the friction member 168.

The warp 10 travels, in a forwardly direction, under the measuring-roll150, over the measuring-roll 153, above and below the splitting-rods151, that is to say, the warpunits pass above and below said rods,through the expansion-comb 155, over the roll 156, partly around theroll T, and over the roll 158 to the warp-beam 151, upon which latterthe now finished warp is finally wound. From this point the warp on thewarp-beam 151 is taken to a frame wherein said beam is mounted and saidwarp is drawn into the harnesses and reed for weaving. The roll 150measures the number of yards of the printed warp which pass in contacttherewith, and the roll 153 measures and marks the lengths of the cutsor pieces, all in the usual and well-known manner.

The splitting-rods 154 separate the Warpunits, which up to this timehave been stuck together in a more or less continuous or unbroken stripor web, so as to prepare them for the subsequent weaving operation forwhich they are intended. It is here that the weavers lease is taken andtransferred to place between the expansion-comb 155 and the draft roll156. lhese operations and their purpose are so well known that noexplanation is here needed.

A. crank 17 6 is provided for the eXpansion-comb 155. The purpose of theeXpansion-comb is to fit as it were the warp-units to the loom-beam, or,in other words, to distribute properly said warp-units on Said beam andcompensate for any difference that may exist between the combined Widthof said units behind said comb and the width or length of said beam.

The object of the draft rolls is obvious, and it need only be observedin connection therewith that said rolls are driven in exact time withthe rest of the machine, so as to prevent any undue strain from beingput upon the printed warp-units.

With the aid of this machine the method can be put into practise in anexpeditious and economical manner, there being one continuous operation,and the most satisfactory results are obtained in the perfect warpturned out. The moving parts being driven and timed as they are thereneed be practically no stops on account of broken Warp.

It should be stated more clearly, perhaps, than has been donehereinbefore, that the adhesive material and the half-dryinol cylinderprepare the warp for printing by rst sticking the warp-units togetherand then drying one side-the side that is to receive the color. It wouldbe impracticable to attempt to print on loose warp, or on warp that waseither dry throughout or moist throughout, as will readily beunderstood.

What 1 claim as my invention, and desire to secure by Letters Patent,is-

1. A method, of printing warp, consisting in causing a plurality ofwarp-units arranged side by side to adhere to each other, in completelydrying such units, so arranged and treated, on one side only, and inapplying printing or coloring material to the dry side thereof.

Q. A method, of printing warp, consisting in causing a plurality ofwarp-units arranged side by side to adhere to each other, in completelydrying such units, so arranged and treated, on one side only, inapplying printing or coloring material to the dry side thereof, and intreating such units to set the color therein.
